🔬 This is a nightly-only experimental API. (int_error_matching)

it can be useful to match errors when making error messages for integer parsing

Enum to store the various types of errors that can cause parsing an integer to fail.

Example

#![feature(int_error_matching)]

if let Err(e) = i32::from_str_radix("a12", 10) {
    println!("Failed conversion to i32: {:?}", e.kind());
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Empty

🔬 This is a nightly-only experimental API. (int_error_matching)

it can be useful to match errors when making error messages for integer parsing

Value being parsed is empty.

Among other causes, this variant will be constructed when parsing an empty string.

InvalidDigit

🔬 This is a nightly-only experimental API. (int_error_matching)

it can be useful to match errors when making error messages for integer parsing

Contains an invalid digit in its context.

Among other causes, this variant will be constructed when parsing a string that contains a non-ASCII char.

This variant is also constructed when a + or - is misplaced within a string either on its own or in the middle of a number.

PosOverflow

🔬 This is a nightly-only experimental API. (int_error_matching)

it can be useful to match errors when making error messages for integer parsing

Integer is too large to store in target integer type.

NegOverflow

🔬 This is a nightly-only experimental API. (int_error_matching)

it can be useful to match errors when making error messages for integer parsing

Integer is too small to store in target integer type.

Zero

🔬 This is a nightly-only experimental API. (int_error_matching)

it can be useful to match errors when making error messages for integer parsing

Value was Zero

This variant will be emitted when the parsing string has a value of zero, which would be illegal for non-zero types.

Trait Implementations

impl Clone for IntErrorKind

pub fn clone(&self) -> IntErrorKind

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)
